    A cylindrical fishing reel has a moment of inertia of I = 6.81à?10-4 kg* m2 and a radius of 3.13 cm. A friction clutch in the reel exerts a restraining torque of 1.49 N*m if a fish pulls on the line. The fisherman gets a bite, and the reel begins to spin with an angular acceleration of 63.7 rad/s2.

    1) What is the force of the fish on the line? and
    2) How much line unwinds in 0.430 s?"
